A magnitude 1.4 earthquake was recorded 28 km (17 mi) ENE of Soledad, CA, at 11:10 am PDT on 28 September 2026 (18:10 UTC). This was a minor earthquake. Quakes this small are rarely felt and do not cause damage.
How big was it?
This earthquake released about 3.8 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 2.4 would have released about 32 times as much.
- Mineral, Virginia 2011 M 5.8 4,000,000× the energy of this one
- Magna, Utah 2020 M 5.7 2,800,000× the energy of this one
- Around the size people start to feel M 3.0 250× the energy of this one
- This earthquake M 1.4 about 3.8 lb of TNT
Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
For this area
The largest earthquake within 50 km since 2016 was M 4.7 on 2019-10-15 — about 92,000 times the energy of this one.
